11 Claims.

This invention relates generally to harvester threshers, and moreparticularly it relates to a self-propelled type of harvester thresher.

Heretofore, in harvester threshers of this type, the machines have beenheavy and difficult to handle. Most generally a heavyframework has beennecessary to support the threshing mecha'- nism and the motor, whichdrives the various parts of the threshing mechanism and also propels themachine over the ground.

With these objectional features in mind,it is the principal object ofthe present invention to provide a novel arrangement of parts which willproduce an improved self-propelled harvester thresher that is small,easy to handle, light in weight, and economical to manufacture.

Another object of the present invention is to provide a novel means forsupporting the threshing mechanism and the motor on the wheeled supportofthe machine; This supporting means permits the threshing mechanism tomove relative to the motor as the machine travels over uneven ground. Inthis way, the usualheavy framework is dispensed with.

Another object of the present invention is to y provide a novel motormounting or supporting means, which also carries the operators platform.One particular advantage of this arrangement is that the machine is,consequently, much lighter in weight.

A further object of the invention is to provide a front support havinglaterally spaced traction Wheels, on which support the threshingmechan'ism and the motor are carried. A steerable wheel is provided atthe rear of the machine between the threshing mechanism and the motor in4such a manner 'that the weight of the machine is balanced about therear wheel. It is also an addi.- tional object in this regard to providea novel steerable wheel construction; arid a novel means for steeringthe wheel.

An additional object of the present invention is to provide an improvedplatform construction in which there is provided an improved feeder. Animproved counter-balancing device is also associatedwith the improvedplatform construction.

In addition, another olojectv of the present invention is to provide anovel driving means for the various parts of the thresher.

-Furthen another object of the present invention istoprovide a'novelmounting for a rubber roll attachment which 'is provided iii-'front ofthe threshing cylinder of the threshing mechanism'.

By virtue of these particular objects and fea.- tures, a compact, yetefficient, self-propelled harvester thresher unit is provided which isespecially advantageous in small harvester threshers and the like.

These and other objects and advantages of the present invention will be-apparent to those skilled in the art after a consideration of thefollowing detailed description of a preferred structural embodiment,taken in conjunction with the accompanying sheets of drawings.

The anglemembers 28 and 29 extend forwardly of the I-beam axle 34, and atransversely positioned housing 43 is secured to the angle members 28and 29 by suitable bracket structures 44. Within the housing 43 isrotatably mounted` a shaft 45, with which is associated a differential46. The shaft 45 extends beyond the ends of the housing 43 and has asprocket 41 secured to each end thereof. As Shown in Figures 1 and 10,one end of the housing 43 is supported from the I-beam axle structure 34by asuitable brace member 48 which is connected between a pair 49 thatare secured on the I-beam axlestructure 34, and between a pair ofspacedplates which aresecured to and extend from the axle housing 46.Bolts 52 secure the brace member 48 to the spaced plates 49 and 5|.Suitable chains 53 are trained around the sprockets 41 provided at theends of the shaft 45, and around the sprockets 31 associated with thetraction wheels 36. The motor 24 is operatively associated with thedifferential 46 on the housing member 43.

The motor 24 consists of an engine 54, a flywheel housing 55, va clutchhousing 56, and a transmission 51, all of which are secured together toform one rigid unit. The usual radiator structure 58 is provided at thefront of the engine 54. The front of the'transmission 51 is providedwith a brake drum 59, which is associated with a shaft which extendsfrom the transmission 51. The clutch housing 58 is provided with a pairof downwardly depending lugs 6| in which there is provided alinedopenings. The motor unit, vby these downwardly depending lugs 8|, ispivotally connected to the I-beam member 365 by a pair of spaced'plates63, which are secured to the I-beam 34, and in which is provided a pairof alined openings, as shown in Figures 4 and i6. A pin 64 is insertedin the alined openings in the lug 6| and in the alined openings in theplate 63. The rear end of the motor 24 is supported on a motor supportv25.

The motor support 25 comprises a longitudinally disposed member 65 whichis secured between a pair of spaced plates 86 that are securedl to thetransversely disposed I-beam 34. The rear or" the member 65 is providedwith a pair of spaced plates 66a, which extend transversely thereto.v'The transverse member 26, which connects the longitudinal member 65 tothe angle members 28 and 29, comprises a piece of square tubing 61, towhich are secured attaching brackets 68 and 69. The bracket 68 issecured to the angle member 28 by bolts 1|, and the bracket 69 issecured to the angle member 29 by bolts 12, as shown in Figure 6. Thesquare piece of tubing 61 extends outwardly between the transverseplates 66a on the longitudinal member t5, and is secured thereto bybolts 13. The longitudinal member 65 is reenforced by an adjustabletruss rod 14. On the square piece of tubing 81, between the longitudinalmember and the separating mechanism 22, is rotatably mounted a steerablewheel 15, which supports the rear of the machine.

The steerable Wheel 15 comprises a member 16, which is mounted forangular movement on a vertical pin 11 secured to the square piece oftubing by a pin 18. The member 13 is provided with a pair of radialflanges 19, with which is associated a wheel hub 8|. Circular rings 82are associated with each of the radial iianges 19 and are enclosed by asheet metal flange 83, which flange and ring are secured to the wheelhub 8| by bolts 84. By virtue of this construction, the wheel 15encircles the transverse member 31, and is angularly adjustable androtatable with respect thereto. As shown in Figure ,1, the wheel 15 ispositioned between the motor 24 and the separating mechanism 22 so thatthe weight thereof will be equally distributed on the wheel 15. An arm85 extends from the hub member 16, and a vertical spindle 86 is securedthereto. The spindle 86 extends upwardly and is journaled in a bracket81, which is secured to the side of the U-shaped housing 21. An arm 88is provided at the upper end ofthe spindle 86.

A mid-point of the longitudinal member 65 is connected to the U-shapedhousing 21 by a transverse motor support 89, on which are providedbrackets 9| and 92. 'I'he bracket 9| is secured to the angle member 28by bolts 93, and the bracket member 92 is secured to the angle member 29by bolts 94. The transverse motor Support 89 extends outwardly laterallyinto association with the longitudinal member 85. As shown in Figure'1,- the outwardly extending portion of the transverse motor support 89is provided with a horizontal bracket and a pair of spaced verticalbrackets 96. The horizontal bracket 95 reenforces an opening 91, whichis provided near the end of the transverse motor support 89. The opening91 straddles the longitudinal member 65, and the brackets 96 are clampedtogether by the bolts 98, and the horizontal bracket 95 is secured tothe top of the brackets 96 by vertical bolts 93. At the end of thetransverse motor support 89 is welded a pair of longitudinally arrangedangles and |02, at the ends of which are provided openings |03. Theengine 54 is secured on the longitudinal angles |0| and |02, as shown inFigure 4.

The engine 54 is provided with downwardly depending legs |04, which arealined with the openings |03 at the ends of the angle members |0| and|02. Bolts |05 are inserted in'the openings in the angle members |0| and|02and secure the legs |04 of the engine 54 to said angle members. Byvirtue of this novel motor mounting, the motor is pivotally mounted onthe wheeled support of the machine, and the rear of the motor is carriedby the longitudinal member 65, which is `in turnA carried by thesteerable wheel 15, and the intermediate portion of the member 65 issupported by the transverse motor support 89. In the event that thelongitudinal member 65 twists as the machine travels over uneven ground,the rear-end of the motor may move upwardly or downwardly about itspivotal connection tothe wheeled support 2|. In this way the usual heavyframework for supporting the motor is eliminated. As shown in Figure 4,the driving shaft, which extends out of the transmission 51, isoperatively connected to a drive shaft which extends from thedifferential 46 by a chain coupling |06. This coupling permits thenormally alined shafts of the transmission 51 and differential 46 tomove relative to one anotheras the motor pivots about the pin 64, whichpivotally connects the motor to the wheeled support. operators platform|01.

As shown in Figure 4, a vertical member |06 extends from the transverseI-beam 34, and a vertical member |09 extends from the longitudinalmember 65. A diagonal brace ||0 consists of angle members that .arewelded to each side of the upper end of the vertical member |09 and therear of the longitudinal member 65. yThe angle `members extend forwardlyand are connected to the upper ends of the vertical members |08 and |09.Brace members ||2 are secured at their lower ends to the vertical member|00 and extend upwardly between the angle members the ends of themembers |08 and ||2 are provided with semicircular portions ||3, inwhich there is provided an opening that is alined with suitable openingsin the angle members Bolts ||4 are inserted through the alined openings,and secure the members |08 and ||2 to the longitudinal angle members Asshown in Figure -3, the front of the operators platform |01 is providedwith an operators station ||4a and a steering wheel ||5, and thecontrols for the various parts of the harvester thresher. The steeringwheel ||5 extends downwardly into a casting ||6 in which there isprovided the usual worm and worm gear assembly, with which is associateda rotatable arm ||1. A longitudinally disposed bar ||8 connects the arm86 on the spindle 86 of the rear wheel 15 with the rotatable arm ||1. Byvirtue of this construction, the operator may steer the .wheel from hisstation H40. A grain tank ||9 is also carried by the operators platform|01. An elevator |2| extends lvertically from the threshing mechanism 21so a's kto convey the threshed grain into the grain tank ||9. h

The unit 23 is positioned transversely ahead of and extends laterally toeach side of the thresh- On the motor support 25 is mounted an As shownin Figures 12 and 13,

ing mechanism 22, and is pivotally connected to the U-shaped housing 21.a transverse platform formed of right and left curved sheet metaltroughs |22 and |23, which extend upwardly and form a rear verticalwall, and in which are rotatably mounted open end augers |24 and |25, asshown in Figures 1 and 9. `Between the open ends of the augers |24 and|25, a longitudinal conveyor |26 is provided in the platform 23. Acrossthe front of the platform is provided the usual cutting mechanism |21which consists of finger guards |28 and a reciprocating sickle |29. Thecutting mechanism |21 cuts the standing grain, and the augers |24 and|25 convey it onto the longitudinal conveyor |26, which in turn conveysthe grain into a feeder housing |3| of the platform 23.

The feeder housing |3| extends rearwardly from the center of theplatform and has an undershot conveyor |32 mounted therein. At the upperend of the vfeeder housing |3| is journaled a shaft |33 on whichsprockets |34 are secured. The shaft |33 extends beyond the sides of thefeeder housing |3| and is journaled in the sides of the U-shaped housing21. As shown in Figure 9, the undershotconveyor |32 consists ofsprockets |34, which are rotatably mounted on a shaft |35 that has alink |36 secured to each end thereof. The links |36 extend rearwardlyandupwardly and are pivotally connected to the sides of the feederhousing |3| by bolts |31. The

rest on the flange |38 of a bracket |39 which side of the feeder housing|3|. A bolt |4| is inserted through alined openings in the link |36 andthe ange |36, and a spring |42 is provided on the bolt |4|, and isadapted to rest against the link |36. By this construction, the lowerend of the undershot conveyor is held against clockwise movement, butmay yieldingly rise in a clockwise direction. It is to be'noted fromFigure 9 that the sprockets |38 are positioned so as to Aoverhang theend ofthe longitudinal conveyor |26, and extend beyond the verticalwalls of the troughs |22 and |23.

`|24 and |25 move the cut material toward the center of the platform 23and onto the longitudinal conveyor |26. Since the lower end of theundershot conveyor |32 overhangs the longitumoves upwardly beyond therear wall of the trough |22, some of the grain would lodge itself in tbelower end of the conveyor |32. To prevent this, a conical-shaped shieldis provided on the rear wan of the trough |22 at each end of theconveyor |32. As shown in Figure 9, the shield |45 is positioned on theback wall of the trough |22 so that, as the lower end of the conveyor|32 moves upwardly. the shield will move the grain around/the end of theconveyor |32. The serrated angle members |44 then grasp the grain andmove it rearwardly along the feeder bottom |3|a of the feeder housing|3| and into the threshing cylinder 3|. A stripper roll |46 is rotatablymounted at the rear of the conveyor |26 so as to clean the cut graintherefrom'and to prevent the conveyor |26 from carrying Athe grainunderneath the conveyor |26. v

The unit 23 is pivotally connected to the front of the U-Shaped housing21 by the shaft |33. As shown in Figures l and 3, this pivotalconnection is stabilized by a structure |41 which extends The unit 23comprises Chains |43, conlnected by serrated angle members |44, aretrained structure |41 ispivotally connected to a bracket |48, which issecured tothe underside of the operators platform |01 in alinement withthe shaft |33. The unit 23 is counterbalanced about its pivotalconnections to the U-shaped housing 21 and the operators platform |01 bya counterbalancing mechanism |49.

The counterbalancing mechanism |49 comprises a longitudinally disposednest of springs |51, one end of which is adjustably secured by a bolt|52 to a transverse member. |53 that is connected between the anglemember 29 and the longitudinally disposed member 65. The other end ofthe nest of springs |5| is connected to a chain |54 which extendsforwardly and is trained around a pulley |55 that is pivotally mountedon a bracket |56 on the I-beam axle 34, as shown in Figure 3. The end ofthe chain |54 is associated with a rock-shaft |51.

|The rock-shaft |51 is journaled in suitable brackets |58, which aresecured to the angle members 28 and 29 forwardly of the member 34. Onthe rock-shaft |51 is secured a cam |59 over which extends the chain|56y which is connected thereto by a pin |61. A pair of arms |62 extenddownwardly from the rock-shaft |51. An arm "rearwardly from the leftside of the unit 23. The

|15. Near the lower surface of the plate member |14 is secured an anglemember |16, on which is secured a bearing |11 in which is rotatablymounted a shaft |18. On the shaft |16 is secured, by a key |19, a rubberroll |8| Since only the mounting for the left-hand side of the rubberroll is shown in Figure 15, it is to be understood that a similarconstruction is provided at the other side of the machine. In theelongated opening |15 is slidably mounted a bearing block |82, in whichis journaled a shaft |63, and on which is secured, by a key |84, arubber roll |85. The outer periphery of the rubber rolls are adapted to`contact each other and are held yieldingly in engagement with oneanother by a pair of springs |86. One end of the springs |86 is adaptedto seat itself on projections |81 provided on the bearing block |82. Theopen end of the elongated opening is connected by a member |98 in whichis threaded an adjusting bolt |89 at the end of which is provided aplate member 19|.

The plate member |9|' is provided with projec- |63 is pivotally mountedon each of the arms |62 and is adjusted with respect to the arm |62 bymeans of a set screw |64, as shown in Figure 3. Referring now to Figure1, it should be noted that the unit 23 is provided with a rearwardly andinwardly extending brace |65, which is connected to the outer ends ofthe troughs |22 and at a mid-portion is arranged parallel to and spacedfrom the troughs |22. The brace |65 is connected' to the arm |63 by ahorizontally disposed link struct-ure |66. The link structure |66 ispivotally connected to the brace |65 by a bolt |61 and to the arm |63 bybolts |68. By virtue of this arrangement of parts, the Weight of theunit 23 tends to rotate the rock-shaft |51 in a counterclockwisedirection wherein the cam |59 on the rock-shaft also moves in `acounterclockwise direction and the chain |54 exerts a force on the nestof springs |5|. When the tension on the nest of springs |5| needs to -bechanged, this adjustment can be accomplished by adjusting the bolt |52.

The unit 23 or, more particularly, the platform is adjusted by a crankwheel |69, which is positioned adjacent the operators station H49. Thecrank |69 is mounted on a suitable support |1| which is mounted on theoperators platform |01. A rod |12 extends from the crank |69 and ispivotally connected to the rear framework of the platform 23 by a bentend portion |13.v The crank |69 and the rod |12 are connected -by theusual rack and pinion type of connection wherein, upon rotation of thecrank |69, the rod |12 is moved upwardly or downwardly, which adjuststhe unit 23 upwardly or downwardly about its pivotal connection to theU-shaped housing 21. It will also be appreciated that the hand wheel |68may be easily adjusted, since the counterbalancing mechanismy |49 aidsin the adjustment ofthe unit 23. At the rear of the pivotal connectionof the unit 23 to the U-shaped housing 21 is mounted a pairlof rubberrolls which constitute the rubber rolll attachment 33, previouslyreferred to.

Referring now to Figures 2j, 14, and 15, it is to be noted that thesides of the U-shaped housing 21- are -reenforced with a plate member|14, in which thereA is provided an elongated opening tions |92 whichare adapted to engage the other end of the springs |86. By adjusting thebolts |89, tension may be increased on the springs |86, which in turncontrols the amount of vertica1 movement of the rubber rolls |85. Thereare many advantages to mounting this rubber roll attachment in thisparticular manner, since the upper roll |85 may be easily and quicklyremoved from the U-shaped housing 21. To remove the upper roll |85, thebracket |88 need only be removed and the entire upper rubber roll |85,and the bearing blocks |82 therefor, may be moved upwardly out of theelongated opening |15. The

lower rubber roll |8| is maintained in the machine, since it serves as abeater for guiding the grain from the feeder housing |3| into thethreshing cylinder 3|. Drive of the various parts of the machine and ofthe threshing wheels 36 and 36a is effected through the motor 24.

On a shaft |93, which extends from the flywheel housing 55 of the motor24, is provided a pulley |93 with which is associated any suitable typeof clutch mechanism |94. As shown in Figure 3, a belt |93b is trainedaround the pulley |93 and around a pulley |95 provided on the shaft ofthe cylinder 3|. As previously explained, the traction wheels 36 and 36aare driven from the shaft 43, which is operably connected tp thetransmission 51 by the connecting means |06. The various parts of theharvester thresher are driven from the pulley |93. Adjacent the pulley|93 and on the shaft |93a is secured a pair of vsprockets |96 and |91.The sprocket |91 effects a drive through a chain |96 to a. thresher fan|99, the lower rubber roll |8|, and the shaft |33 of the undershotconveyor |32.` The chainv |98 is trained around a sprocket 20|, which isprovided on the shaft of the fan |99, and around a sprocket 2 02provided atthe left end off/the lower rubber roll |8|, and around a,sprocket 203, which is secured to the shaft |33. The chain |98 effectsthe drive of the rubber roll |8| and the undershot conveyor |32 in thedirection indicated by the arrows in Figures 9 and 14. From the shaft|33 various parts of the platform 23 are driven. On the shaft |33 issec-ureda sprocket 204. At each side of the platform 23 are rotatablymount ed shafts 205 and 206. On the shaft 206 is secured a sprocket201,A and a. chain 208 is trained about the sprockets 204 and 201 so asto drive the shaft 206. At the left end of the shaft 206 is mounted agear box 209, from which extends a shaft 2|0 that is operativelyconnected to Ithe assen-i cutting mechanism |21 in the usual manner.Adjacent the gear box 209 is mounted a sprocket 2| I, and a sprocket 2|2is journaled on the end of the auger |25. A chain 2|3 is trained aroundthe sprocket 2| l, the sprocket 2|2, and drives the auger |25. The shaft205 is driven from the shaft 206 through the rear shaft 2|4 0f thelongitudinal conveyor |26. As shown in Figure 3, a sprocket 2|5 isprovided on the end of the shaft 2|4, and a chain 2|6 is operativelyconnected therewith and with a suitable sprocket provided on the shaft206 and a chain tightener sprocket 2|1. Through the chain 2|6 the shaft2|4 is driven. As shown in Figure 2, on the other end of the shaft 2|4is provided a sprocket 2|8, and a sprocket `2|9 is provided at` the-endof the stripper roll shaft |46. A chain 2|8a is trained around thesprockets 2|8 and 2|9 and around a suitable sprocket provided on theshaft 205, and around an idler sprocket 22|. In this manner the shaft206 is driven by the chain 208, from which shaft the longitudinalconveyor |26 and the stripper 'roll |46 are driven.' From the drive ofthe longitudinal conveyor |26, and through the chain 22|, the shaft-205y is driven. As shown in Figure 2, the 'auger |24 is driven by asuitable connec- 'tion similar to the connection provided at the leftside of the platform 23.

The controls for the various drives of the harvester thresher areprovided on the operators platform |01 near the operators station ll4.As shown in Figures 2, 3, and 4, a clutch pedal 222 is pivotally mountedon the operators platform |01,

'and is connected to a clutch providedin the clutch housing 56 by a rod223,. Adjacent the clutch pedal 222 is pivotally mounted a brake pedal224 that is connected to the brake 59 by a rod 225. The gear shift lever226 extends upwardly from the transmission 51, through an opening in theoperators platformfl01, and near to the operators station H45. The gearshift lever 226 starts and stops the drive to the traction wheels 26 and2lia in the usual manner. A lever 221 controls the clutch |94. A rod 228connects the lever 221 and the clutch |94, by which, upon movement ofthe lever 221, the pulley |93 and the gears |96l and |91 are `startedand stopped.

From the foregoing description it should be apparent that an improvedself-propelled type of harvester thresher has been provided. By virtueof this construction, the principal object of the invention has beenaccomplished by providing a small and light-weight harvester thresher.The novel mounting of the motor on the harvester `thresher has alsocontributed to the construction of a light-weight and easily handledharvester thresher. The machine may be easily steered from the operatorsstation by virtue of the novel wheel mounting which supports the rear ofthe entire machine. The improved feeder device permits the platform tobe closely connected to the separating mechanism of the harvesterthresher.

- and is so constructed as to eiciently convey the grain from theplatform into the threshing mechanism. A rubber roll attachment has beenprovided for the threshing mechanism, which maybe quickly and easilyremoved if so desired.

It is to be understood that,v while a preferred construction embodyingthe principles of the present invention has been shown in the drawings,the invention is not to be limited to the What is claimed is:

l.
